1763 The WM9705, WM9712 and WM9713 is a highly integrated hi-fi CODEC
1764 designed for smartphone applications. As well as audio functionality
1765 it has on board GPIO and a touchscreen functionality which is
1766 supported via the relevant subsystems. This driver provides core
1767 support for the WM97xx, in order to use the actual functionaltiy of
